POWER-TRANSIVHTTING MECHANISM.

SFECIFICATION forming part of Letters Patent NO. 742,738, dated October 2'7, 1903. Application filed December 29, 1902. Serial No. 13 6,932. (No model.)

To all whom it may concern:

Be it known that I, LOUIS H. REDETZKE, a citizen of the United States, residing at Echo,

in the county of Yellow Medicine and State of.

Minnesota, have invented certain new and useful Improvements in Power-Transmitting Mechanisms, of which the following is a full, clear, and complete specification, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to a power-transmitting mechanism embodying certain novel and peculiar features and details of construction and relative disposition of parts, as hereinafter particularly set forth, illustrated in the drawings, and set forth in the appended claims.

he object of my present invention,broad1y speaking, is to provide a mechanism for operating very heavy machinery at a uniform low rate of speed with the least expenditure of power and operating expenses and also to provide such a device in which the several elements are compactly arranged and assembled, so as to occupy but a small space and be of ready access and capable of easy adjust-.

ment, regulation, and repair.

Another object is the provision of a powertransmitting mechanism which will be simple in character, compact in form, easily operated and maintained, and whereby the operator will be enabled to control its operation, so that its work will be performed with certainty and precision; and still another object is the provision of a power-transmitting mechanism composed of interdependent and cooperating parts so arranged as to produce a constant and unvarying source of power.

Other objects and advantages will appear from the following specification and from the drawings forming a part thereof.

I attain the above and other objects and other important and subordinate features by the mechanism and arrangement of parts illustrated in the accompanying drawings, in which like indices refer to and denote like parts throughout the several views.

Referring now to the drawings, Figure 1 shows a perspective view of my entire mechanism. Fig. 2 shows an end elevation of same, and Fig. 3 shows a central cross-sectional elevation of same.

The numeral 1 represents the main shaft of my device, which is supported near each end revolubly in pillow-blocks A, which latter are mounted on a framework B of any suitable construction, substantially as shown in the drawings.

The numeral 2 denotes a circular hollow drum surrounding the shaft 1, of a length slightly less than the distance between the supporting-posts of the framework B, and is provided with flanges 2 2 around each end, as shown. The drum 2 ma be formed of strips of wood lying parallel with each other and secured in place at their ends by the flanges 2 2, substantially as shown, or said drum may be formed entirely of metal or the like, if desired.

The numerals 3 3 denote two endless parallel ribs secured to the inner surface of the drum near one end thereof, and l represents a hub secured to the shaft 1 and extending from near one of the pillow-blocks to near the center of the distance between the two pillowblocks, as shown.

The drum 2 is connected to the hub 4: by the spokes 5 and the braces 6 crossing each other,thus forming a wheel carried by the axle 1, substantially as shown.

The numerals 7 7 denote two endless parallel rails'or tracks, secured to and extending around the inner surface of the drum 2, parallel to the ribs 3 and on the opposite end of the drum therefrom.

Between the rails 7 7 and parallel therewith is an endless cog-gear rail 8, forming a traction-surface.

0' represents a motor-car mounted on four flanged traction-wheels 0, adapted to travel onthe rails 7 7, and a round cog-gear wheel 10 is mounted from the under side of the center of the motor by hangers 9 down therefrom, carrying thefaxle 11, on which the wheel 10 is revolubly mounted. The wheel 10 is adapted to mesh with and travel on the cog-rail 8 and is operated by any well-known gearing located in the casing 0- such, for instance, ,as an electrical motor, more clearly seen in Fig. 3 of the drawings.

This motor has its armature-shaft provided with a small gear 2, which meshes with the upper edge thereof, by applied thereto to propel the car 0'.

which power may be It will 9, extending K now be apparent that the machinery in the car 0 may be started to revolve the wheel 10, and by reason of the wheel 10 meshing with the rail 8 the car will travel on the track 7 7, and as the car advances the drum 2 will be revolved, thus allowing the car to remain almost stationary with reference to the frame. Machinery to be operated may be geared to the projecting end of the shaft 1.

My invention is perfectly adapted to accomplish the results for which it is intended, and it is evident that changes in and modifications of the specific construction herein shown and described may be made and that analogous parts may be used to accomplish the same results without departing from the spirit of my invention or sacrificing any of its many advantages, and the specific construction of the details of my mechanism in which novel features are embodied may be variously changed without alteringthe essential principles, which are claimed as new.

Having now fully shown and described my invention and the best mode for its construction to me known at this time, What I claim as new, and desire to secure byLetters Patent of the United States, is-

1. The combination with the frame and the shaft journaled thereon, of a drum mounted on said shaft, a 'pair of rails secured to said drum, a rail arranged between said firstnamed rails, a car mounted on said firstnamed rails, and an operating means carried by the car engaging the last-named rail.

2. In a device of the type set forth, adrum comprising in combination with its bodyportion, a hub extending approximately centrally of said body portion, spokes secured to said hub and body portion, respectively, and a plurality of rails secured to the inner face of said body portion at one side of said spokes, the intermediate rail being formed with teeth, in combination with a car, mounted on the outer of said rails, a cog-wheel journaled in said car and meshing with the teeth of the intermediaterail, and means mountedin said car and engaging said cog-wheel for operating the same.

In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.

LOUIS. H. REDETZKE.
